1.0 Executive Summary

This report summarizes the results of limited sampling of suspect hazardous materials including asbestos-containing construction materials, soils with naturally-occurring asbestos (NOA), lead-based paint, and polychlorinated biphenyls (PCBs) for the planned demolition and relocation of the San Mateo Medical Center (SMMC) Water Tower, located near 3701 Hacienda Street, San Mateo, CA. The sampling was conducted on September 27, 2016 by Tucker Kalman, CAC #15-5384, CDPH of SCA Environmental, Inc. (SCA). The planned activities include demolition of the existing water tower and its relocation approximately 50 feet to the northwest. In addition, new utility trenches will be excavated between the new water tower and the San Mateo County Medical Center in order to install electrical utilities and water lines. This activity will impact the soils around the water tower, fill material to a depth of 4 feet beneath the asphalt parking lot, and the asphalt parking lot and associated base rock. To evaluate the extent of hazardous materials present, SCA conducted sampling of the water tower for suspect asbestos-, lead-, and PCB-containing materials. In addition, sampling of the soils to be impacted as part of the project and base rock was conducted for naturally occurring asbestos (NOA) along the proposed trench lines and at the site of construction for the new water tower. The asphalt was also sampled to determine asbestos content.

The following summarizes the results.

Asbestos in Construction Materials

A summary of asbestos-containing materials and non-asbestos containing materials is tabulated in the Table: Materials Matrix Report (MMR). Note the following:

1. Only one material (caulking with mastic at the base of the steel water tank on top of the concrete platform, SCA Sample ID CAULK-1) was identified as having >1% asbestos.

2. No Trace (<1%) asbestos-containing materials were identified.

Prior to any renovations or demolition, the National Emission Standard for Hazardous Air Pollutants (NESHAP) mandated by the Environmental Protection Agency (EPA) and locally enforced by the Bay Area Air Quality Management District (BAAQMD) requires:

1. A structure be inspected for asbestos-containing materials prior to demolition; and 2. Asbestos containing materials subject to damage or which will be made friable be removed.

Identified asbestos-containing materials to be disturbed by the proposed renovations should be abated by an Asbestos Abatement Contractor following CalOSHA Class II work procedures Naturally-Occurring Asbestos in Soils No soils or base rock sampled were found to contain asbestos. Lead The yellow and green paints present on the water tower and steel tank were found to contain measurable concentrations of lead. Dust control procedures are required throughout the demolition/renovation of painted elements to comply with the Cal/OSHA regulations under 8 CCR 1532.1. Disposal of these items would be as non-hazardous waste given the total lead contents and/or


regulations regarding disposal of lead. Torching of coated metals requires spot abatement prior to such activities. Loose and peeling paints should be stabilized prior to demolition, and debris segregated from the waste stream and characterized to determine leachability prior to disposal. Disposal of these materials may be as RCRA or California hazardous waste pending receipt of analytical waste characterization data. Additional sampling and analysis for leachable lead content by the Consultant during demolition will be required for waste characterization. Polychlorinated Biphenyls (PCBs) No sampled materials were found to contain PCBs above the laboratory's detection limit of 0.5 parts per million (ppm), well below the hazardous waste standard of 50 ppm for PCB.


2.0 Introduction

This report summarizes the results of limited sampling for asbestos-containing construction materials, soils with naturally-occurring asbestos (NOA), lead-based paint, and PCBs at the SMMC Water Tower, 3701 Hacienda Street, San Mateo, CA. The sampling was conducted on September 27, 2016. The purpose of the limited sampling was to determine the presence of regulated and/or potentially hazardous materials in the Project area, that are required to be addressed in the planned demolition of the existing water tower, construction of a replacement water tower, and trenching of utility trenches to a depth of four feet bgs. Materials addressed in the survey include:

Asbestos-containing materials (ACM); Asbestos-containing construction materials (ACCM); Naturally-occurring asbestos (NOA) in soils to be disturbed and base rock; Lead in paints; and PCBs in building materials.

3.0 Methodology

3.1 Asbestos-Containing Construction Materials Asbestos sampling was performed in a fashion designed to minimize exposure of the surveyor or occupants of surrounding buildings to airborne asbestos fibers. Samples were typically removed from the substrate utilizing a knife or chisel, the sample material was then placed into an airtight plastic vial. The vial's exterior was labeled with a unique sample I.D. The vial was then stored in a plastic bag. Samples of asphalt were collected with the assistance of a coring contractor to remove an intact core of asphalt and allow for access to the underlying base rock and soils. Water was applied during coring to prevent any dust generation. Samples of suspect materials were collected generally using triplicate sampling procedures. Under these procedures, the first sample is analyzed. If it tests positive for asbestos (>1%), the analysis is suspended for further samples of that material. If the first sample tests only trace positive (between 0.1 to 1%), or negative, then the second and third samples are analyzed sequentially, in order to determine the possible presence of asbestos. If all three samples test negative, the material is considered as non-asbestos. If one or more samples test "trace" positive (<1%), the material is considered to be trace positive. If one or more samples are positive for asbestos, the material is considered positive. All asbestos samples collected were submitted to Reservoirs Environmental, Inc., (REI) in Denver, Colorado for analysis by polarized light microscopy (PLM) with dispersion staining (DS/PLM). The Bay Area Air Quality Management District's (BAAQMD), the Federal Environmental Protection Agency's (EPA), and California Environmental Protection Agency's (Cal/EPA) regulations all specify the DS/PLM method. 3.2 Asbestos-Containing Soils and Baserock Sampling of soils and base rock for asbestos was performed in a fashion designed to minimize exposure to the surveyor or the occupants of surrounding buildings to airborne asbestos fibers. Samples were collected by utilizing a hand auger in order to bore to 4 feet below ground surface (bgs). Samples of soil and rocks were collected from the entire 4 foot column and composited into on sample. Baserock samples were collected at the surface of the soil where asphalt had been cored in the parking lot.

Upon collection, all samples were transferred to Ziploc plastic bags and transported to Analytical Labs of San Francisco (ALSF) under chain-of-custody documentation to be analyzed for asbestos using CARB 435 (1,200 point count). ALSF is an NVLAP- and ELAP-accredited facility for bulk asbestos analysis.

3.3 Lead-Containing Paints

Lead contents were measured by collection and analysis of bulk paint samples. Samples were ana-lyzed by EPA Method 6020 (ICP/MS) by McCampbell Analytical, Inc.

3.4 PCB Containing Items PCB content was measured by collection and analysis of bulk samples. Samples were analyzed by Gas Chromatography-Electron Capture Detector (GC-ECD) by McCampbell Analytical, Inc. by EPA Method 8082 with sulfuric acid permanganate (EPA 3665) cleanup.


4.0 Applicable Standards

4.1 Asbestos-Containing Materials ACM is defined by EPA regulations as those substances containing greater than 1% asbestos. The BAAQMD and the Cal/EPA provide local enforcement of these regulations. Friable ACM with greater than 1% asbestos needs to be disposed of as asbestos waste. Prior to renovation of a Building, the BAAQMD requires abatement of friable ACM, as well as non-friable ACM that may become friable during renovation (practically, this means all non-friable ACM). Federal Occupational Safety and Health Administrations (OSHA) regulations, locally enforced by CAL/OSHA, define ACM as substances that contain greater than 1% asbestos. Cal/OSHA also mandates special training, medical exams, personal protective equipment and record keeping for employees working with ACM. If a material contains less than 1% asbestos but more than 0.1% asbestos, the material may be disposed of as non-ACM, but the Cal/OSHA requirements would still have to be followed regarding workers' protection and Contractor licensing. "Trace" materials are currently regulated in California and require the following:

• Removal using wet methods; • Prohibition of removal using abrasive saws or methods which would aerosolize the

material; • Prompt clean-up of the impacted zone, using HEPA-filtered vacuums, as applicable; • Employer registration by Cal/OSHA for removal quantities exceeding 100 sq. ft. per

year; and • Cal/OSHA Carcinogen Registration by the Demolition or Abatement Contractor

impacting such materials.

4.2 Naturally-Occurring Asbestos Naturally occurring asbestos (NOA) has been identified in at least 44 of California's 58 counties. The Asbestos Airborne Toxic Control Measure (ATCM) for Construction, Grading, Quarrying and Surface Mining Operations was signed into State law on July 22, 2002, and became effective in the Bay Area Air Quality Management District (District) on November 19, 2002. The purpose of the regulation is to reduce public exposure to NOA from construction and mining activities that emit dust which may contain NOA. The ATCM requires regulated operations engaged in road construction and maintenance activities, construction and grading operations, and quarrying and surface mining operations in areas where NOA is likely to be found. If identified, the regulation includes requirements for the Contractor to employ dust mitigation measures in order to reduce and control dust emissions. Depending on the proposed use of the site and future construction activities, sampling at depth may be required to verify if NOA is present at the site. In addition, if asbestos concentrations exceed 1% asbestos, all work must be performed utilizing Class II work procedures with AHERA-trained personnel. Workers involved with removal of soil are required to adhere to all CalOSHA requirements (e.g., training, notifications to CalOSHA prior to work, personal monitoring, etc.).


4.3 Lead-Containing Paints Since elemental lead is a suspect carcinogen and known teratogen and neurotoxic in high doses, lead-containing materials need to be identified prior to the on-set of demolition activities. Using combinations of engineering controls and personal protective equipment, lead-containing materials can be removed safely. Several sources of applicable standards are listed as follows:

1. Lead exposures in the workplace are regulated by Cal/OSHA, which has certain regulatory requirements for identifying and controlling potential lead exposures. Currently applicable regulations for the construction industry have been adopted by Cal/OSHA (8 CCR 1532.1) from the Federal OSHA regulations. The current OSHA 8-hour Permissible Exposure Level (PEL) for lead is 50 µg/m3.

2. Current EPA and Cal/EPA regulations do not require LBP to be removed prior to

demolition, unless loose and peeling. Provided that the paint coatings are securely adhered to the substrates (i.e., non-flaking or non-peeling), disposal of intact demolition debris can generally be handled in California as non-hazardous and non-RCRA waste, pending receipt of waste characterization testing following demolition.

In California, loose and peeling LBP or other wastes require characterization and

testing for leachability. Disposal requirements are outlined as follows:

3. The major definitions of LBP or lead-coated surfaces are listed as follows:

a. HUD defines LBP as paint that contains either >0.5% by weight of lead, or >1 mg/cm2.

b. Consumer Product Safety Commission (CPSC) prohibits the manufacturing

of paint that contains more than 90 ppm of lead. Note that adherence to Cal/OSHA's Construction Lead Standard is required for all

paint with any measurable lead content.

4. Lead is on the "Proposition 65" list, given its toxic potential in causing reproductive

hazards. 5. The California Department of Public Health (CDPH) requires the use of Certified

Lead Workers and Supervisors for lead abatement projects at public Buildings with a greater than 20 years expected life or whenever work is completed specifically to abate Lead-Based Paint as defined by HUD. The CDPH certification requirements do not apply to industrial sites; however, dust controls and personnel protection are still required under 17 CCR Sections 35001 through 36100.

4.4 PCB-Containing Items Cal/EPA regulates the disposal of PCB containing materials. Any PCB containing material over 1 ppm must be disposed of in accordance with Cal/EPA.


5.0 Results and Conclusions 5.1 Asbestos in Building Materials The detailed results (including quantities found in each location) are shown in the attached Table 1: Materials Matrix Report. Asbestos-sample locations are shown on drawings included as Attachment 1, and all analytical reports are included in Attachment 2.

1. Only one material (caulking with mastic at the base of the steel water tank on top of the concrete platform, SCA Sample ID CAULK-1) was identified as asbestos-containing as part of this investigation.

Prior to any renovations or demolition, the National Emission Standard for Hazardous Air Pollutants (NESHAP) mandated by the Environmental Protection Agency (EPA) and locally enforced by the Bay Area Air Quality Management District (BAAQMD) require:

1. A structure be inspected for asbestos-containing materials prior to demolition; and 2. Asbestos-containing materials subject to damage or which will be made friable be removed.

Identified asbestos-containing materials to be disturbed by the proposed renovations should be abated by an Asbestos Abatement Contractor following CalOSHA Class II work procedures.

5.2 Naturally-Occurring Asbestos in Soils No soils to a depth of 4 feet bgs or base rock sampled were found to contain asbestos above the labor-atory's detection limits. Results of the soil and base rock samples are included in Table 1: Materials Matrix Report. Asbestos-sample locations are shown on drawings included as Attachment 1, and all analytical reports are in-cluded in Attachment 2. 5.3 Lead-Containing Paint Coatings Results of the bulk samples collected are included in Table 1: Materials Matrix Report and laboratory reports are included in Attachment 3. The yellow and green paint samples collected were found to contain measurable concentrations of lead. Concentrations ranged from 180 to 880 milligrams per kilogram (mg/kg). As lead was identified in the paints, for the purpose of complying with the Cal/OSHA lead in construction regulation (8 CCR 1532.1), all coated surfaces shall be considered to contain some lead and require demolition dust control procedures for compliance with Cal/OSHA's Construction Lead Standard under 8 CCR 1532.1. The aforementioned regulation contains requirements for lead air monitoring, work practices, respiratory protection, etc., that are triggered by the presence of even very low levels of lead. In addition, based on the California Total Threshold Level Concentration (TTLC) hazardous waste standard, the paints may be classified as hazardous wastes. Additional sampling and analysis for leachable lead content by the Contractor during demolition will be required for waste characterization. Disposal of these materials may be as RCRA or California hazardous waste pending receipt of analytical waste characterization data.


None of the applicable regulations require removal of lead paint prior to renovation if the paint are securely adhered to the substrates (i.e., non-flaking or non-peeling). Disposal of the demolition debris in this case can be handled as non-hazardous and non-RCRA waste after the loose and flaking paint have been removed, as long as demolition practices do not compromise worker safety. Conventional demolition techniques should be employed for all painted surfaces with the Contractor complying with applicable OSHA and Cal/OSHA statutes regarding:

• Worker awareness training; • Exposure monitoring, as needed; • Medical examinations, which may include blood lead level testing; and • Establishing a written respiratory protection program.

5.4 PCB-Containing Items No sampled materials were found to contain PCBs above the laboratory's detection limit of 0.5 ppm. Results of the bulk samples collected are included in Table 1: Materials Matrix Report and laboratory reports are included in Attachment 3.


6.0 Limitations and Exclusions

SCA warrants that this survey was performed using due care and state of the art techniques. Beyond this, SCA does not warrant or guarantee the survey. Despite the care exercised, some materials may not have been identified, or may have been incompletely identified. This condition may occur due to renovations or original construction practices that concealed older materials, and/or visually similar materials with different compositions. This document is not a stand-alone document; abatement of materials is recommended to be completed under the oversight and design of an AHERA-accredited Project Designer and Certified Asbestos Consultant. Although due care is exercised in the course of the survey, concealed materials may be found in the course of performing the abatement or demolition; a contingency budget should be included in any cost estimates prepared to cover unexpected conditions.

- STLC and TCLP extractions require 2 days to complete; therefore, all TATs begin after the extraction is completed (i.e., One-day TAT yields results

in 3 days from sample submission).

NOTES:

- MAI assumes that all material present in the provided sampling container is considered part of the sample - MAI does not exclude any material

from the sample prior to sample preparation unless requested in writing by the client.
